One of the strategies we use to minimize this bias is to restrict the analysis to schools that assign students to classrooms in a manner statistically indistinguishable from random assignment. Using data for 5th grade, we consistently find significant returns to teacher experience in both math and reading and to licensure test scores in math achievement. We also find that the returns in math are greater for socioeconomically advantaged students, a finding that may help explain why the observed form of teacher-student matching persists in equilibrium. aHardcopy version available to institutional subscribers aSystem requirements: Adobe [Acrobat] Reader required for PDF files. aMode of access: World Wide Web.0 aPrint version record 7aI2 - Education and Research Institutions2Journal of Economic Literature class. 7aJ4 - Particular Labor Markets2Journal of Economic Literature class.1 aLadd, Helen F.1 aVigdor, Jacob L.2 aNational Bureau of Economic Research. 0aWorking Paper Series (National Bureau of Economic Research)vno. w11936.40uhttp://www.nber.org/papers/w1193640uhttp://dx.doi.org/10.3386/w11936
